According to the World Resources Institute (WRI), already in 1993 nearly one-quarter of the vegetated land area of the Earth has been highly disturbed by human activity and an additional 28 percent has been moderately disturbed. Over a century later, human misuse of natural resources and disturbance of natural environmental systems is pushing the Earth to the limits of its capacity. Numerous natural resources are being consumed at rates that far exceed the speed at which they can be regenerated or replenished. Uncontrolled or excessive exploitation through e.g. deforestation, overgrazing (Pastoral Management Systems), excessive cultivation due to inappropriate agricultural projects, proliferation of invasive aliens, inadequate irrigation practices, man-made fires, irresponsible tourism and other forms of land resource exploitation such as mining or oil and gas surveys can have a profound effects on the natural environment. There is no doubt, that the anthropogenic impact on the natural environment caused by the unsustainable exploitation of available natural resources should be studied, analyzed, and understood to avoid environmental mistakes in the future. "Human Impact" extremely visual :-( - just have a click on the National Geographic Banner and have a look for yourself. |
